SPECIFICATION forming part of Letters Patent No. 378,358, dated February .21, 1888.

ducting-wires being,` secured, respectively, by l T @ZZ whom, it may concern.-

Be itknown that I, HARRY M. DoUnLnDAY, a citizen of the United States, residing at Columbus, Franklin county, Ohio, have invented new and useful Improvements in Incandescent- Electrieunp Fixtures, of which the following is a specification.

My invention relates to improvements in those ineandescent-electriclamp xtures in which the lamp is suspended by means of the conducting-wires from a ceiling-block and the objects of my improvements are to provide a ceiling-block consisting of a non-conducting disk having electrical connections and a shell having means of ready attachmentto said disk and adapted to support the pendent conducting-wires of the lamp. Y

In the accompanying` drawings, Figure Iris an elevation of mydevice. Fig. II is an axial vertical section in a plane parallel to the elevation. Fig. III is a plan of the disk.

Similar letters refer to similar parts throughout the several views.

Ais a non-conducting disk,which has screws a., to which is attached, by means of bayonetjoints b b, the shield B, said shield having secured within its lower orifice, by means of pins c c, a button, G, of wood or other insulating material. This button is flared at its upper end in order to rest upon a shoulder, d, oi' said shield, thus affording additional strength for the supporting of the conducting-wires E E, which pass through an orifice, D, said conthe binding-screws e e to the plates F F. A safety-catch of a fusible wire, f, connects plate F with F. Plates F F F are riidly attached to the insulatingdisk A by means of screws h. The plates F F have binding-screws e" e, which screws are capable of receiving conducting-wires t' A ceiling-block such as above described provides a simple and cheap means of suspension of a lamp and contains all the necessary connections, doing away with the usual separable plug and socket.

I am aware that it is not broadly new to fasten the cut-out and other` electrical connections to a ceiling-block whereon a chandelier is hung, and that various devices have been contrived for making automatic contact when a lamp-plug is placed in its socket.

I claim as new and of my invention* rlhe combination of the ceiling-block A., having electrical connections and cut-out fixed thereto, metal shield B, removably connected to said ceiling-block, non-conducting perforated button C, supported at the base of said shield, and electric-lamp wires E, suspended from said button and connected to the electrical connections on the ceilinghlock, substantially as and for the purpose set forth.
